Martin Mystery - Season 3 Episode 15

Kaitlin has fallen victim to her shadow and, as usual, it is up to Martin and Billy to save the day. They have found out that since the people who were safe slept in the light, that is the thing that the shadow creatures fear. With the help of the Legendex, they realize that the shadow creatures' leader, Barok the Faceless One, wants to take over the Earth, but needs all the humans in his realm before he can cross over–and when he does, the gateway will close forever. When Billy is also taken, and Martin is the last being on Earth, the showdown begins.
